Nostrodomas Wasn't Using a Secret Method When Formulating Prophecies

There's evidence nostrodomas was using a secret method that he didn't tell anybody about when he was formulating his prophecies. This idea has been explored particularly by peter le missurier, especially in his book, nostro domus bibliomancer. Part of his argument is that nostro damas definitely wasn't getting all this information by doing astrological calculations. In fact, nostroDomas wasn't even a competent astrologer. And he was attacked, in his own day by professional astrologers such as a, for example, one named videl for being incompetent in the craft le messerie. Write videl is quite specific.
